To all whom it may concern:

Be it known that 1, JOHN A. LovnLY, a citizen of the United States, anda resident of Middletowmlin the county of Orange and State of New York,have invented certain new and useful Improvements in Coping-Joint Seals,of which the following is a specification.

My invention relates to the joints between the blocks of wall copings,and the main object thereof is to provide a waterproof seal for suchjoints whereby the present objectionable water stains on the wallbeneath the coping joints are eliminated and the effect of the water incourse of time upon the usual joint fillers tending to disintegrate thesame is prevented.

Where mortar is used in such joints the upper surface of the mortar isgiven a finish with a suitable tool, resulting in a channel or gutter inwhich the water gathers, and this is true also where lead is tamped intothe joint with the further objectionable feature that the edges of thelead are formed into knife edges of a very brittle characteristicwhereby portions of the edges break away and defeat the very object ofthe seal, this tamping tending to crystallize the lead so as to bereadily broken.

With my seal, however, the upper surface is convex instead of concave,thereby eliminating the gutter above referred to and, in a manner to beexplained, the possibility of the knife edges above referred to isovercome, thereby insuring a permanent and waterproof joint, not aloneat the top of the coping block but at the sides thereof as well.

My invention is fully described in the following specification, olfwhiclt the accompanying 'drawings form a part, in which like charactersrefer to like parts in each of the views, and in which Figure 1 is afragmentary view of a wall provided with coping blocks sealed at theirjoints with my invention;

Fig. 2 is an enlarged side elevation of my seal detached from thecoping, as supplied from the factory, showing also the manner ofpreparing the ends of a strip for the protection of the side of a joint;

Fig. 8 is a fragmentary section taken through a coping joint and showingmy seal in a preliminary stage of installation; and

Fig. 4 is a similar section, showing the seal installed, as on the lineit-A of Fig. 1.

Referring to the drawings. 5 represents a wall having coping blocks 6thereon and the joints 7 between which it is desired to seal, theseblocks usually being of stone and the adjacent ends of which are usuallyrather rough, presenting surface irregularities which, if not thoroughlypacked by the filler, permit the passage of water through the joint.

'My seal, as provided by the manufacturer, consists of a T-shaped stripof soft metal, such as lead, formed of a sheet 8 the middle of which,longitudinally, is bent upon itself as shown at 9 at each side of acentral longitudinal line to form a top member 10 and two lower members11, the two sides of the sheet being thenbent angularly as shown at 12to form, jointly, a

web member 13 of double thickness preferably greater than the width ofthe interstice between the coping blocks with which it is to be used,and it will be noted that the head member 14 formed by the members 10and 11 is convex in cross section at the top and the edges 9 are formedof the surface metal and not of a cut edge, this being a very importantcharacteristic of the seal.

The strip may be provided in various lengths ready for cutting intodesired lengths or strips of desired lengths for the thickness ofdiflerent walls may be provided, each of these lengths being theequivalent of the width of the coping plus the vertical height of thecoping at both sides.

When a mechanic desires to install one of the lengths he cuts the webmember 13 at 15 and at 16 at right angles to removeaportion of said web,the distance from the end of the strip to the junction of the cuts 15and 16 being equal to the vertical thickness of the coping, orapproximately so, whereby, when the portion 17 is bent downwardly tocarry the lines 15 and 16 into juxtapositlon, as shown at the left ofFig. 2, the head member 14 of the portion 17 is perpendicular to thehead member of the main port on of the strip and the end of the strip 1sm the plane of the lower edge of the web member 13 of the main portionof the strip, or approximately so, and the web member 13 is preferablymade of a vertical width equalling the vertical thickness of the coplng.

In the installation of the seal, after the ends have both been turneddownwardly as shown at the left of Fig. 2, I place glaziers putty or theequivalent in the channels at each side of the web member 13 beneath orinside of the head portion 14 and insert the web member into the spacebetween the ends of the coping blocks, after which the head member istapped with a hammer or the like to drive the seal into the intersticebetween the coping blocks to its limit.

The putty l8 fills the spaces at each side of the web member beneath thearched head member and the soft metal of the seal is squeezed into thesurface irregularities of the adjacent coping block ends and, because,of the smooth edges 9, no crystallizing,- or breaking away, occurs aswould be the case if these edges were raw cuts and, further, the arch ofthe head member tends to not alone shed water itself but also tends tomaintain the soft metal at the edges 9 in close contact with the outersurface of the coping.

My invention is very simple, though highly efficient, very practical,and comparatively inexpensive, and I may provide the same in differentdimensions to suit different conditions, but I will at all times formthe seal of sheet metal whereby a T- shape is presented in cross sectionof doubled material, with the head member As a new article ofmanufacture, a coping joint seal consisting of a blank of soft metalfolded and bent to form a T-shaped strip including a double-walledconvex or arched head and a double walled web depending therefrom thelower wall of the head concaved, and the web having angular cut-outportions adjacent each end whereby the end portions of the head may bebent at right angles to the intermediate portion, to close the aforesaidcut-out portions of the web, and form a continuous web adapted to fitwithin the space between coping blocks across the top and ends thereof.
